Washington, September 12 ( ANI ): Have you ever wondered why some
people find it so much easier to kick the butt than their peers?

New research shows that vulnerability to smoking addiction is
shaped by our genes.

A study from the Montreal Neurological Institute and Hospital - The
Neuro, McGill University shows that people with genetically fast
nicotine metabolism have a significantly greater brain response to
smoking cues than those with slow nicotine metabolism.

This new finding that nicotine metabolism rates affect the
brain's response to smoking may lead the way for tailoring smoking
cessation programs based on individual genetics.

Scans show areas of brain activation in response to smoking cues in
people with fast nicotine metabolism and slow nicotine metabolism. Brain
regions are more activated in individuals with fast nicotine metabolism.

"The finding that nicotine metabolism rate has an impact on
the brain's response to smoking cues supports our hypothesis that
individuals with fast nicotine metabolism rates would have a greater
brain response to smoking cues because of close coupling in everyday
life between exposure to cigarettes and surges in blood nicotine
concentration," said clinician-scientist Dr. Alain Dagher, lead
investigator at The Neuro.

In other words they learn to associate cigarette smoking with the
nicotine surge," he added. ( ANI )
